hey guys, i removed the a/c system from my integra and now my check engine light comes on immediatelly after i start the car, what could be wrong? I removed the lines back to the firewall, the big piece that i believe is called the compressor, the belt that ran it, and a small tank looking thing that was by the washer fluid. Does the light come on because it detects that there's no longer a/c? anything i can do? thanks in advance!!!

 

Find out what code is stored, causing the check engine light. That will tell you the problem. You may have disconnected something by accident.
